FILLING DEVICE Filed June 2, 1930 gwumt w Geog: Mawen Patented July 14, 1931 GEORGE W. OWEN, OF BALTIMORE, MARYLAND FILLING nnvrcn Application filed. .Tune 2, 1930. Serial No. 458,999.

This invention relates to a device for facilitating the filling of fountain pens.

An object of the invention is to provide means associated with an ink bottle whereby a fountain pen may be quickly and completely filled.

Another object is to provide a device for the purpose stated, which will receive and securely hold a stopper in a normal manner such as to preclude accidental removal thereof and subsequent spilling of ink from the bottle.

Another object is to provide a simplified yet efficient and inexpensive sealing element associated with an ink bottle having an ink collecting chamber, for the purposes above stated.

Another object of the invention is to provide a pen filling-device comprising a readily replaceable and inexpensive sealing element.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is an elevational view, partly in cross section, of the device of the present invention.

Fig. 2 is a top plan view taken on line 22 of Fig. 1.

Fig. 3 is a cross sectional view of a modified form of sealing element.

The ink bottle 3 comprises an enlarged body portion 4 and a narrow neck 5 which provides an ink collecting chamber 6 wherein the ink may collect upon inversion of the bottle when'a fountain pen has its pointed end inserted in the opening 7 of the sealing element 8. The sealing element is preferably in the form of a perforate washer of soft rubber or other suitable material, the lower or inner face 9 of which is adapted to abut the annular edge 10 of the ink bottle neck. The opening 7 of the sealing element is made slightly smaller than the forward end of a given size of fountain pen, thereby rendering the sealing element capable of effecting a sealing about the end of the pen. Although a given size of sealing element is found to accommodate pens of various diameters, it is readily evident that sealing elements having various sized openings 7 may be employed.

The neck of the ink bottle preferably is provided with external screw threads 12 adapted to cooperate with the internal screw threads 13 of a cap 14. The upper portion 15 of the cap comprises a cylindrical wall 16 bounded by the narrow lower flange 17 and '55 the side upper flange 18. The top of the cap is provided with a circular opening 19 which is larger than the opening 7 in the sealing element- The annular flanges 17 and 18 form with the wall 16 a pocket or recess 20 which securely holds the sealing element within the cap. It will be noted that the pocket portion of the screw cap is slightly larger in diameter than the screw threaded portion thereof. When it is desired to replace the sealing element, it is necessary only to unscrew the cap from the bottle and to then press the sealing element out through the screw threaded portion of the cap. It should be noted thatthe upper annular flange 18 extends centerward sufliciently to overhang the top annular edge 10 of the bottle, so as to provide a backing or resistence member for the force exerted upon the sealing element when the screw cap is tightly screwed onto the bottle.

The stopper 21 is designed to effectively cooperate with the sealing element for sealing the ink bottle and precluding accidental displacement of the stopper. The stopper comprises a head 22 and a plug portion 23 conso centric therewith, the curved outer walls of which are in the form of a frustumof a cone, which walls converge toward the head portion 22. Free end 24 of the plug is chamfered to facilitate insertion of the plug into the opening of the sealing element. By means of the above construction, the liability of the plug to become loose in the opening, is eliminated, and removal thereof is resisted by the outwardly tapering or diverging walls.

In Fig. 3 is shown a modified form of sealing element, the opening 7 of which is provided with an annular recess 25, which rovides a plurality of sealing surfaces 26. suitable number of recesses 25 may be provided in order to increase the number of sealing surfaces. It is to be understood that the invention is not to be limited to the herein described means for holding the sealing element in abutment upon the top edge of the bottle, it being readily evident that means other than the screw threads could be employed for the purpose.

To fill a fountain pen by means of the device of the present invention, it is necessary only to insert the forward end of a fountain pen in the opening 7, invert the bottle and pen in order to cause collection of the ink in the ink collecting neck of the bottle, and to then actuate the self-filling means with which fountain pens ordinarily are equipped. The bottle and pen may then be righted, and the pen removed from the opening 7 Removal of the pen serves to clean the forward end thereof of any ink tending to cling thereto. The device of this invention 'may be manu- .factured at a very small cost, and the sealing element thereof may be readily employed when necessary.v

hat is claimed is:

1. In combination a container for fluid substance having a hollow fluid collecting chamber with an opening therein, a perforate cap for the container, a flat perforate resilient cleaning and sealing element receivable in the cap the perforation therein being of lesser diameter than the perforation of the cap, means on the cap for holding the sealing element in position upon the edge of the fluid collecting opening,and cooperative means on the cap and containerfor removably securing the cap to the container.

2. ,In combination an invertible container for fluid substance having ahollow fluid collecting chamber with an opening therein, a perforate cap having a pocket portion, a flat perforate resilient cleaning and sealing element received in the pocket of the cap and adapted to partly close the opening in the collecting chamber, the opening of the collecting chamber and of the sealing element being in concentric relation, a flange on the cap arranged for disposition directly above the edge of the opening in the collecting of the sealing element being substantially concentric with the perforation of the cap.

5. In a pen filling device the combination of a container for fluid substance having an opening therein, and a flat relatively thin perforate resilient cleaning and sealing washer partlyclosing the opening and adapted for yieldingly receiving in the perforation thereof the forward end of a flllable pen.
